The Second Update Weekend (in which our hero makes modest progress)
This weekend, like last weekend, will be at least in part dedicated to making progress on getting Macs upgraded to 10.5. Bear in mind that the problems so far have nothing to do with getting the Macs upgraded (said upgrade being a smooth process) but with getting the HP Z3100 working smoothly on the upgraded machine.
I have now fallen back to the least desirable path, which is to make a clean install of 10.5 on the Mac Pro, and then get the printer working, and then reinstall all the applications. The big problem will be reinstalling Photoshop, because I will have to jump through the phone call hoops to get Photoshop re-registered.
